|Coordinator||GKN AEROSPACE SWEDEN AB - Avd 9005|
|Funding from Vinnova||SEK 3 787 000|
|Project duration||November 2019 - December 2022|
|Venture||National Aeronautical Research Program 7|
|Call||Research project in aviation technology - spring 2019|
Purpose and goal
The operation of the aircraft engine is limited by the aerodynamic ability of the compressor to increase the pressure on the air and the vibrations the leaves can withstand without being exhausted. A closer integration with the fuselage, increased operating envelopes and distortion is expected to be more pronounced in future aircraft. The project will develop and validate tools for analyzing operating limits and improving aeroelastic margins over large operating areas for primarily compressors and fans in aircraft engines.
Expected results and effects
The project will increase knowledge of how turbo engines are designed to cope with conditions in future aircraft applications. Analysis models that can be used to optimize the machine are the result of the research.
Planned approach and implementation
The development is done by developing simplified models that, together with advanced analysis tools for simulation and experimental data, can be used to analyze aeroelastic properties over relevant operating ranges.
